# Docker compose Kafka, Zookeeper and Kafka manager
Gist inspired by this one intending to be an updated version of it : https://gist.github.com/17twenty/d619f922ab209f750630824f7c6836e3
## Install
- Create the environment variable that contains our host name (IP address) :
```
$ export EXPOSED_HOSTNAME=$(ip addr | grep 'state UP' -A2 | tail -n1 | awk '{print $2}' | cut -f1  -d'/')
```

- Create the folders :
```
$ mkdir -p zookeeper/{data,logs}
```

## Run
- Execute the docker compose :
```
$ docker-compose -f docker-compose.yml up -d
```

- Access Kafka Manager : http://localhost:9000/.

- Add a new cluster.

- Name it as you like (**Localtest** for example).

- IP : localhost:2181

- Kafka version (corresponding here to the Kafka version inside the image : **wurstmeister/kafka:1.0.0**). But as I write this Gist, the latest Kafka version available in Kafka Manager is **0.11.0.0** so I select this one, but it's sufficiently compatible with the 1.0.0 version of Kafka according to this topic: https://github.com/yahoo/kafka-manager/issues/451

- Tick **Enable JMX Polling** in order to see the metrics of the topics

- Tick **Poll consumer information** to know the consumer of a topic (it may not work)

- Tick **Enable Active OffsetCache** to see the offsets

And then save it.

:sparkles: This is done ! :sparkles:

## Uninstall
- Stop the containers and remove them :
```
$ docker-compose -f docker-compose.yml stop && docker-compose -f docker-compose.yml rm -vf
```

## Tips
- Remove content of Docker volumes (we need to do this trick to remove hidden and non-hidden files) :
```
$ rm -rf zookeeper/{data,logs} && mkdir -p zookeeper/{data,logs}
```
